Acer chairman JT Wang said that the Taiwanese company is expecting 30-35% of its notebook PCs to have touch-screen functionality by the end of the year, marking an increase from its current 25% use this quarter.

"Price and supply for touch panels provide some constraints now, but that will ease and boost the penetration of touch devices," Wang said.

While the PC market is at its lowest shipment rate in almost four years, Wang also expects it to continue to decline as a whole this year. However, he has predicted that notebooks and tablet PCs will experience a combined 10-15% sales increase.

Acer shipped 1.2 million tablets between January and March 2013, and is aiming to push between 5 and 10 million by the end of the year.
